Why use potassium formate drilling fluid for drilling construction? The manufacturer tells you
Drilling is one of the more technical tasks. The choice of drilling fluid should be adapted to local conditions according to various links. It is not that the more money you spend, the better the effect. According to the geothermal survey results, the local geological hydrothermal conditions are obtained, the geothermal drilling design process and construction plan are determined, and the corresponding drilling rig and other corresponding materials are selected. Why use potassium formate drilling fluid for drilling construction? The manufacturer Chuandong Chemical tells you.
Drilling fluid is a special problem when drilling. It is a common chemical at the construction site. So why use potassium formate as a drilling fluid when drilling?
First of all, the use of potassium formate drilling fluid at the drilling site can clean the bottom of the well, flush the formation, cool and lubricate the drilling tool, and at the same time carry the cuttings and make them have a suspension effect. The potassium formate drilling fluid can also rely on the pressure of the liquid column to balance the anger pressure, prevent blowouts, and stabilize the well wall to prevent drilling collapse.
Secondly, there is another reason why potassium formate drilling fluid is used for drilling, because it can carry out cutting logging by circulation and help the screw or turbine drill to transmit power.
Field application results show that potassium formate inhibits clay hydration. So gradually began to apply potassium formate to drilling and completion fluids, especially in high-density drilling and completion fluid systems, and achieved good results.
In general, drilling fluids can achieve low aqueous solution activity. In the presence of semi-permeable membranes, the activity of drilling and completion fluids is an important factor for maintaining formation stability. NaCl and CaCl2 are basically saturated at a concentration of about 30-40%. The solubility of potassium formate is higher, which can reach more than 76%, which shows that it can achieve lower solution activity and better inhibition operation. This is very important for the stability of the well wall. Therefore, it is safer and more effective to use potassium formate drilling fluid for drilling construction.
