Abstract

A drilling mud screen system, comprising: a hollow body having a first end, a second end and a first centerline from the first end to the second end; a drilling mud inlet having a second centerline forming an angle with the first centerline and extending to the first centerline, wherein the drilling mud inlet is offset from the first end of the body; a drilling mud outlet at the second end of the body; a drilling mud screen access port at the first end of the body; an end cap, disposed within the drilling mud access port to close and seal the drilling mud access port; a plug, disposed within the first body between the first end cap and the first drilling mud inlet; and a drilling mud screen, disposed within the body between the drilling mud inlet and the drilling mud outlet is disclosed. Methods of installing and using the drilling mud screen system are also disclosed.

Dependent claims

A drilling mud screen system, comprising:

(a) a first body having a first end, a second end and a first centerline from the first end to the second end;
(b) a first drilling mud inlet having a straight extension, the drilling mud inlet and the straight extension having a second centerline forming a first angle with the first centerline and extending to the first centerline, wherein the first drilling mud inlet is offset from the first end of the first body and wherein the first angle is from about 20-degrees to about 120-degrees;
(c) a first drilling mud outlet at the second end of the first body;
(d) a drilling mud screen access port at the first end of the first body;
(e) a first end cap, disposed within the drilling mud access port to close and seal the drilling mud access port;
(f) a drilling mud screen comprising:
(i) a second body having a first end and a second end;
(ii) a second drilling mud inlet at the first end of the second body;
(iii) a filter having a first end, a second end, and openings, wherein the filter is fluidly connected to the second end of the second body via a first connection and/or a first end retaining ring;
(iv) a second drilling mud outlet at the openings of the filter;
and
(v) a second end cap fluidly connected at the second end of the filter via a second connection, wherein the second end cap is an inverted cone or an inverted cone with holes or slots;
(g) wherein the drilling mud screen is disposed within the first body between the first drilling mud inlet and the first drilling mud outlet;
(h) wherein the first drilling mud outlet is adapted to be fluidly connected to an inlet of a vibrator hose or an inlet to a standpipe or at any point in the standpipe.
