永553低渗砂砾岩区块一体化(IPM)钻井技术

Integrated Project Management (IPM) Drilling Technology of Yong 553 Low Permeability Glutenite Block

摘要:

永安油田永553区块目的层为沙四段，以含砾砂岩、砾岩为主，为低孔低渗油藏。前期施工井存在钻进速度慢、开采程度低、经济效益差等特点。针对永553低渗区块开发现状及开发难点，对该区块进行了一体化(IPM)钻井方案设计，并对钻井设计进行了优化。通过优化钻井技术，钻井提速明显，提高了井身质量，延长了油井寿命。永553低渗区块IPM钻井项目的成功实施，说明IPM钻井模式对于提高油井质量、节约钻井成本、提高经济效益是行之有效的。

Abstract:

The target section of Yong 553 block in Yong’an oilfield is Sha-4, low permeability reservoir mainly containing glutenite and conglomerate. There are problems such as low drilling efficiency, low exploitation degree and poor economic benefit in early construction. To realize overall high quality and efficient development in Yong 553 block of Yong’an oilfield, IMP was carried out. The overall development program was designed for low permeability 553 block according to the development status and difficulties. By optimizing drilling design, the drilling efficiency was obviously improved with higher quality of wellbore and longer service life of oil well. The successful practice of IPM in Yong 553 low permeability block shows that IPM drilling model is an effective way to improve the quality of oil well, save drilling cost and increase economic efficiency.
