【摘要】：层位预测精度是制约现场作业质量和成本的关键因素。为进一步满足海上油气田在勘探开发高成本压力下对层位预测精度的更高要求,在参考地质层位预测方法的基础上,结合渤海油田丛式井开发的特点,利用防碰扫描原理分井段选择参考井,利用油田勘探开发阶段获取的钻、录、测井资料数据绘制单层顶、底界等深线图和单层等厚度图等地质图,根据新井井轨迹在构造图上投影等手段,形成了一套基于钻、录、测井资料的层位预测的新方法,并在应用中获得成功。该方法不但提高了层位预测精度和作业质量,而且降低了作业风险和成本,对当前低油价形势下海上油气田的高效开发具有重要意义。
[Abstract]:The accuracy of horizon prediction is the key factor that restricts the quality and cost of field operation. In order to further meet the higher requirements of horizon prediction accuracy in offshore oil and gas fields under the high cost pressure of exploration and development. On the basis of reference geological horizon prediction method, combined with the characteristics of the development of cluster wells in Bohai Oilfield, the reference wells are selected according to the principle of anti-collision scanning, and the drilling and recording obtained in the exploration and development stage of oil fields are used. A set of geological maps based on drilling and recording has been formed by using logging data to draw geological maps such as single-layer topping, bottom boundary isobaric lines and single-layer isobaric maps. According to the projection of the new well trajectory on the structural map, a set of geological maps is formed. The new method of horizon prediction of logging data is successful in application. This method not only improves the precision and quality of horizon prediction, but also reduces the risk and cost of operation. It is of great significance for the high efficiency development of offshore oil and gas fields under the situation of low oil price.
