根据人工裂缝特征优化油井压裂地质方案

近年来大庆油田外围地区地质储量得到动用，每年依靠压裂投产的井逐渐增多，由达西定律可知，在油层厚度一定的情况下，措施井的渗透率是影响产量的关键参数，油井压裂可以改善油井周围地层渗透性，消除近井地带油层污染，从而提高油井产能，而人工压裂的成功与否主要取决于裂缝的导流能力和裂缝的几何形态，为此，根据台105地区地质特征，结合低渗透油田开发实际，本着经济有效的开发原则，从人工裂缝特征，方位对开发效果的影响等方面，论述了优化油井压裂地质方案技术的方法，改善了低渗透油田的开发效果。

Fracturing Plan to Optimize Oil Well by Artificial Character in Tai105 Region

Reserve in place of external region has been developed in recent years .The wells depending on fracturing to produce increase more and more while the residual thickness of oil reservoir which can be fractured gradually decreases. It is well known that the purpose for measured oil well is to improve its productivity . Oil well`s permeability is the key parameter to its production under the condition of specified reservoir thickness from Darcy Law. Fracturing to oil well can increase its productivity by improving formation permeability around the oil well. However, whether artificial fracture is successful or not is up to the factors below: fracture conductivity and geometry. Therefore, we optimize fracturing plan of oil and water well combining with artificial fracture character in Tai105 region. On the basis of development law of economy and validity, and combined with the development practice in Tai105 region, this paper optimizes fracturing plan for oil well by studying artificial fracture character and bearing that have influenced on development result. It is essential to improve the development result of low permeability oilfield.
