裂缝性储层化学堵水技术研究

油田在长期的注水开发过程中，储层由于具有可溶性，或胶结性差的原因，会形成裂缝性储层，而裂缝性储层在调整吸水剖面时，凝胶类的调剖剂在矿场应用出现了调剖效果差，有效期短的问题，因此，油田现场急需研究一种堵塞强度高，封堵效率高的裂缝封堵剂。在室内我们研究了一种以水泥为主要材料的裂缝性化学堵水技术，该技术可以有效的封堵裂缝性储层，同时具有成本低、封堵效率高、封堵强度高的特点，具有很高的矿场应用价值。

Study a technology on water shutoff of Fractured formation

Develop in long-term water flooding in the course in the oil field,since the reservoir having solubility, cement bad cause of nature, meeting form the fractured formation. when adjusting water absorption section of the fissured formation, the forming gel of profile modification material is having poor profile control and short term of validity, therefore, the production of oil field is badly in need of a material of plugging material with high strengh and high efficiency of plugging. Indoor we study a technology of plugging of fissured formation with cement as main material. this technology has effective plugging characteristics of fissured formation with low costs, high strengh and high applying value.
