针对桩西油田148块断块油藏复杂断块油藏开发过程中存在油井能量下降,结蜡,油井压力下降快、单一的压裂无法有效解决油层改造的问题等,积极开展相关技术研究和试验,进一步配套了压裂改造油层、径向射孔技术、调整注水技术、自洗井清防蜡技术等技术手段,大大提高了该断块的开发效果,改善了油层的渗流能力、补充了地层的能量、提高了油藏的驱替效率,具有较好的借鉴意义。
Aiming at the problems such as energy decline, waxing, rapid decline of oil well pressure during the development of complex fault block reservoirs in 148 block fault block reservoirs in the Puxi oilfield, the single fracturing can not effectively solve the problems of oil layer reforming, and actively carry out relevant technical research Test, and further supporting the fracturing and transformation of the reservoir, radial perforation technology, adjust the water injection technology, self-washing wells paraffin wax technology and other technical means to greatly improve the development of the fault block effect to improve the seepage capacity of the oil reservoir, added to the formation Of the energy, improve the displacement efficiency of the reservoir, has a good reference.
