石油壓裂支撐劑簡介
? ? ? ?石油支撐劑是一種陶瓷顆粒產品,具有很高的壓裂強度,主要用于油田井下支撐,以增加石油天然氣的產量,屬**產品。此產品利用優質BAUXITE、煤等多種原材料,陶瓷燒結而成,是天然石英砂、玻璃球、金屬球等中低強度支撐劑的替代品,對增產石油天然氣有良好效果。
? ? ? ?目前常用的支撐劑主要有石英砂、鋁釩土陶粒砂及樹脂包覆的復合顆粒等。由于石英砂成本低,同時密度較低易于泵送,被大量使用,但石英砂強底低、球度差,降低裂縫導流能力,不適用于閉合壓力高的深井。樹脂包覆石英砂的復合顆粒,球度有**,耐腐蝕性比較強,導流能力也較好,但產品保持期短,造價過高,在成本至上的**推廣不易,而采用鋁釩土陶粒工藝的陶粒支撐劑,密度高,球度好,耐腐蝕,耐高溫,耐高壓,同時成本可以得到較好的控制,因此越來越廣泛的被油氣田所采用。實踐證明,使用陶粒石油支撐劑壓裂的油井可提高產量30-50%,還能延長油氣井服務年限,是石油、天然氣低滲透油氣井開采、施工的關鍵材料,不但能增加油氣產量,而且更能延長油氣井服務年限。
? ? ? ?石油支撐劑又叫石油壓裂支撐劑。在石油天然氣深井開采時,高閉合壓力低滲透性礦床經壓裂處理后,使含油氣巖層裂開,油氣從裂縫形成的通道中匯集而出,此時需要流體注入巖石基層,以超過地層破裂強度的壓力,使井筒周圍巖層產生裂縫,形成一個具有高層流能力的通道,為保持壓裂后形成的裂縫開啟,油氣產物能順暢通過。
石油支撐劑的性能
? ? ? ?1、支撐劑要有足夠的抗壓強度和抗磨損的能力,能耐受注入時的強大壓力和摩擦力,并有效地支撐人工裂縫。
? ? ? ?2、支撐劑顆粒相對密度要低,便于泵入井下。
? ? ? ?3、支撐劑顆粒徑要符合不同油井的設計要求,一般為0.4~0.8mm,圓度和球度大于0.9,而且顆粒均勻,表面光滑,其濁度值應小于100度,以獲得盡可能高的導流能力。
? ? ? ?4、支撐劑顆粒在溫度為200攝氏度的條件下,與壓裂液及儲層流體不發生化學作用,酸溶解度較大允許值應小于7%。

A brief introduction of oil fracturing proppant
Oil proppant is a kind of ceramic particle product, has the very high fracturing strength, mainly used for oilfield downhole support, in order to increase the output of oil and gas, environmental protection products.This product use high quality BAUXITE, coal and other raw materials, ceramic sintering and become, is a natural quartz sand, glass balls, metal balls substitute for middle and lower strength proppant, to produce more oil and gas has a good effect.
At present commonly used proppant are mainly of quartz sand, aluminium vanadium and soil clay sand and resin coated compound particles, etc.Because of the low cost of quartz sand, low density and easy pumping, used by a lot, but quartz sand strong low bottom, sphericity, reduce fracture diverting capacity, shall not apply to high closure pressure of deep well.Resin coated compound particles of quartz sand, sphericity is improved and corrosion resistance is strong, diverting capacity is better also, retention period is short, but the product cost is too high, the cost of todays promotion is not easy, and adopts aluminium vanadium and soil in the process of ceramsite ceramsite proppant, high density, good sphericity, corrosion resistance, high temperature resistance, resistance to high pressure, at the same time can get a better cost control, so more and more widely used by oil and gas fields.Practice has proved that using ceramsite proppant fracturing of oil production of oil Wells can improve the 30-50%, can also extend the oil and gas Wells length of service, are oil, natural gas of low permeability oil and gas well drilling, the construction of key materials, not only can increase oil and gas production, and more oil and gas Wells can extend the length of service.
Oil proppant also called oil fracturing proppant.When mining in the oil and gas Wells, high closure pressure and low permeability ore deposit after fracturing treatment, split oil and gas layers, oil and gas from collecting in the crack formation of the channel, it requires fluid into the rock at the grass-roots level, to more than the strength of the formation fracture pressure, make the cracks around the wellbore rock strata, forming a channel with high flow ability, to maintain the formation of crack opening after fracturing, oil and gas products through smoothly.
The performance of the oil proppant
1, proppant should have enough compressive strength and wear resistance ability, can endure the strong pressure of injection and friction, and effectively support the artificial fracture.
2, proppant particles lower relative density, easy to pump into the underground.
3, proppant grain size to meet the design requirements of different oil Wells, general is 0.4 ~ 0.8 mm, roundness and sphericity is greater than 0.9, and uniform particles, the surface is smooth, the turbidity value should be less than 100 degrees, as much as possible in order to obtain high flow conductivity.
4, proppant particles under the condition of the temperature of 200 degrees Celsius, and the fracturing fluid and reservoir fluid chemistry does not occur, acid solubility maximum allowable values should be less than 7%.
Oil fracturing proppant purpose
Fracturing proppant can be widely used in deep well, high pressure oil and gas layer fracturing.By the high quality bauxite as the king to raw material after crushing finely ground into powder, match with various additives, repeated practice, granulating, polishing, high temperature sintering, the product has high crushing strength, low density, good sphericity, high smoothness, diversion ability, etc.Supported by the oil exploration and development research institute of China langfang branch evaluation laboratory tests, each performance index of SY/T5108-2006 completely, SY/T6302-1997 standards, is at a leading level.
