产品简介 Product Introduction

通过泵压将其送至井底待测点进行测量，测量完成仪器自浮到井口液面，无需测斜绞车。自浮系列产品品种齐全，适用范围广，尤其是碳纤维载体浮筒，重量轻，浮力大，在泥浆比重较小（可以小至1.0）的直井中得到了广泛应用，解决了地层压力小的油气井钻进中测斜和泥浆比重要求的矛盾 This tool is put down to the bottom of the survey point by the pump pressure. After survey completes, the tool will float off to the wellhead depending on its own buoyancy, no winch is needed. The self-floating series can be applied in full wide range of conditions. Especially the carbon fiber pontoons, light weight and strong buoyancy, are widely used in the vertical wells of small mud specific gravity (can be as less as 1.0), which resolves the resolve contradiction between survey and mud weight when drilling small formation pressure oil and gas wells.
